This tag refers to public-key algorithms based on problems that quantum computers can't solve efficiently. Existing algorithms such as RSA, Diffie-Hellman, and ECDSA are known to be breakable using Shor's algorithm on quantum computers. Symmetric-key algorithms generally don't fall under this category.
This tag refers to public-key algorithms based on problems that quantum computers can't solve efficiently. Existing algorithms such as RSA, Diffie-Hellman, and ECDSA are known to be breakable using Shor's algorithm on quantum computers.
Currently, the only standardized public-key encryption algorithm is NTRU (by IEEE), and the only standardized digital signature schemes are XMSS and LMS (specs published by IETF, hardware implementations approved by NIST).
Symmetric-key algorithms generally don't fall under this category.
